I made a soundtrack mod for "Killing Floor" to replace it with the Quake 2 soundtrack. I have it as a .zip file, and it's ready to go. But I have no idea how to upload to Steam Workshop. I've asked in TWO different game hubs already, but no one has responded! It's like uploading to Steam Workshop is a taboo topic or something. I've also googled "How to upload to Steam Workshop", but results that were relative to Skyrim modding appeared. So, any help please? I'd appreciate it, thanks in advance!
